To all whom it may concern:

Be it lmown that I, WALTER B. PIERSON,

.a citizen of the United States, residing at a novel manually operated device by means of which dishes of all kinds may be quickly and easily washed, thus saving time and labor as compared with the ordinary hand washing methods. An important object is the provision of a device of this character which includes novel adjustable racks for holding shallow plates, saucers and the like and other racks for holding deeper dishes and cups.

An additional object is the provision of a device of'this character which will be simple and inexpensive to manufacture, efiicient ment in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in

which:

an outer tank or receptacle 10 w Figure 1 is a side elevation of the tank having a rack disposed therein,

Figure 2-is a longitudinal sectiong Figure 3 is a plan view, Figure 4 is a horizontal section showing a lan view'of the rackfor shallow dishes,

igure 5 is a detail view of the handle, Figure'6 isa perspective view of a tray, Figure 7' is a plan view of the rack for degp dishes and cups,

igilre 8 is a ban r mounting, and

Figure 9 is a plan view of the bottom of either rack.

Figure 10 is a top plan view of a modified form of rack. v

Figure 11'is' a detailsectional view-show inghan adjustment feature.

ferring more particularly to the drawings "I have shown my device as comp-rising ch is cylindrical in shape and which may have any dimensions may also be constructed of any suitable detail view showingthe cup found advisable and which material, such as galvanized iron, enamel.

were or the like. At its upper edge this receptacle is formed or provided with handles 11 so that it may be easily carried about when necessary. The to of this receptacle is designed to lie close by a cylindrical member 12 which is formed. with a bead 13 designed to engage at the upper edge of the receptacle 10 for preventing the top from slipping in. This top is formed centrally with a circular hole 14 for'a purpose to be described. v v v .In' connection with this receptacle and top I provide a rack for plates, saucers and other flat dishes, this rack includin a bottom 15 and a side wall 16 prefera 1y perforated to permit free passage of water. The bottom 15 is provided with a pflurality of upstanding pins or projections 1 for a purpose to be described. Extending transversely of the open top of this rack is a series of wires 18 which have one end connected with screws 19 adjustably mounted through the side and which have their other ends connected with coil springs 20 connected with the opposite side. By adusting the screws 19 the spring tension on the wlres may be regulated. The plates to be washed are inserted between. the successive wires 18 with their lowermost portions engagingcertain of the pins or projections 17 which will operate to preventt epl-ates from sliding down or slipping about. This rack is provided with a bail 21 formed at its center with what may be called an open loop 22 with which is detachably engageable a h 0k 23 formed on the lower end of a rod 24 wliich terminates in a handle 25.

I also make use of a rack for holding deeper dishes and cups, this rack being of the same construction as that previously described,except that the wires 18 are located much farther apart so that there will be room between them for hooks 26 upon which 7 cups may be hung. I

' In the use of .the device plates, saucers and other shallow dishes are inserted between the wires 18 of he first described rack water should preferably have a temperature,

of about 150 Fahrenheit as this tempera-v ture is found to be most advantageous for hot water or soap suds so that a thorough cleansing action will be had. The deeper dishes such as those used for serving vegetables and the like are washed in the same manner but are of course placed in the other rack in which the Wires 18 are farther apart and it will be noted that owing to the provision of the springs 20 in the racks-differences in the depth of various dishes will be taken care of as the Wires may yield. After washing as above described the top 12 is removed and the rack is pulled up somewhat, that is out of the water and fresh hot water is poured over the dishes to efiect rinsing, after'which the rackfull of dishes is set on the tray 27 to drain. I have found that after a very short time the dishes will dry themselves, though if a gloss is desired it may be advisable to rub the disheswith the usual towel just before they become thoroughly dried.

In Flgure 10 I have shown a slight modifi cation of the rack structure designed particularly for use in the kitchens of small families especially where it is not desired to 3 um separate racks as those above described for holding dishes of different types. In

this. form the cylinder 28 is provided at its top with arseries 0; light coil springs 29 spaced apart as shown instead of the wires and springs previously described. This permits placing plates. saucers and also deep dishes 1n the same rack, it being also possible to force cups between the springs and engage them upon suitable-hooks 26 on the inside of the cylinder.

From the foregoing description and a study of the drawings it will be apparent that l have thus provided a simply constructed and consequently inexpensive device for washing dishes with far less labor than is required in the ordinary hand washing method. It is to be noted that l have made ample provision for takin care of dishes of all kinds so that no han ling will be required other than placing the dishes within the racks and subsequently removing them.

While l have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

I claim: I

p 1. Adish rack comprisin a rim member, a plurality of spaced para el wires extendmg thereacross, coil springs connected at one end with the rim and at their other ends with said wires respectively, and means for adjusting the wires longitudinally for varymg the tension of said springs.

2. A dish rack comprising a member, a plurality of spaced parallel wires extending thereacross, coil springs connected atone end with the-rim and. at their other ends with said wires respectively, and means for adjusting the wires longitudinally for varying the tension of sa1d springs, said means comprising nipples rotatably engaged through holes in the rim and having threaded bores, the ends of the wires being threaded for engagement within said bores.

In testimony whereof I a my signature.
